Serial Lati-595,099, filed Octoberl'l, 1922, and of. which my present invention is,a continuation in part. Y

a journal box having portions shaped to conform to and arranged toengage portions of a car truck side frame. the particular shape of saidportions permitting theiise of a maximum amount of metal in the sideframe at the critical points therein and also providing for theeconomical and efiicient casting of the journal box in the mold.

Another object of the invention is to produce a journal box providedwith a portion adapted to fit within a journal. box recess in the sideframe, said journaTbox being formed with means adapted to permit thejournal box to be detachablv con nected to the side frame and maintainedin bearing-like contact with the walls of said recess, said meansinvolving longitudinally arranged lugs adapted to embrace the outerfaces of the opposite sidewalls of the side frame and receive easilyinserted connecting pins or bolts.

A further object of the invention resides in the provision of a journalbox having inwardly and upwardly converging side walls suitably mergedinto the top of the journal box at different inclinations or angles.

whereby in the manufacture of the journal box it will! be possible topart the mold on a line passing through the center of the attaching lugsfor that portion of the journal box at the front and rear of said lugs,and also permit of the portion of the side, walls between the attachinglugs being shaped sothat said portion, which is preferably cored inpractice, is parted on a line below said first named parting line of thel the claims: r An object of my invention is to provide car axleillustrated.

mold, thereby aflording greater cross secti n re the d ce i e ram w l inwhich the journal box recess. is formed.

instill further object of the invention is to provide a ournal boxpossessing the ady niase-= v a ove n te the. nte ior o the journal boxbemgmamtained of a shape and size capable .of receiving the standard,equipment including the A; R. A. brass.

Withthese, and other objects in view, the invention further consists inthe combination and arrangement of the several parts, together with themethod o f'manufacturing my improvedjournal box.

In the drawings illustrating the; invention. the scope whereof is"pointed out in Figure '1. is a View partl vation and partly in sectionof my im proved journal box, thesame being shown attached to a portionof the cartruckv side frame. 1 I

Figure 2 isja vertical sectional view transversely through the sideframe showing, my improved journal box with the upper portion engagingthe journal boxrecess of the side frame. the car axle and other parts ofthe journal box being omitted. I V

Figure 3 is, a top plan view of, the jourin side eleake 1 nal, box withparts in horizontal section,

opposite portionsof the side walls or abutments of the journal. boxrecesses being I shown in section. with the atta ching pins .or boltspassing therethrough.

Figure el is a'detail one-halfhorizontal sectional view on the line 4:of Figure 2, a portion of the brass and wedgebeing shown in positionabove. the portion of the Figure 5 is a fragmentary vertical sectionalview on the line 55 of F ignre 4.

Figures 6 and 7 are similar views on the lines .6-.6 and 7-'7 of Figure4.

Referring to the drawingsin which similar reference characters designatecorresponding parts in the several views, my improved journal box I isshown attached to a truck side frame 2 preferably formed with an innerwall 3and an outer wall. 4. 5 A journal box recess 5 is provided neareach end of the side frame, said recess being provided.withoppositeabutment Walls 6 and 7 which are inwardly and upwardly converged saidabutment walls being merged into and'united with the top wall 8 of thejournal box recess. The wall portions of the side frame forming thejournal box recess are preferably constructed from marginal inturnedflanges .9 formed integrally with the side walls 8 and 1, said flangesbe- .ing preferably united or abutted within the invention, however, Ihave shown the journal box associated with a journal box recess formedin the pressed metal side frame, the usual brass 10 and wedge 11beingfitted about the car axle within the journal box, all in theusualmanner.

The journal box 1 is provided with side walls 12 united at their lowerends by the I bottom 13 and at their upper ends by the top Portions ofthe journal box are of the usual construction and may be-provided withsuch parts as the journal box lid and dust-guard, not shown. The topwall portion 14 is preferably formed with a plurality of intersectingtransversely and longi- 'tudinally disposed ribs 15 having their upperedges preferably shaped to conform to the contour of the upper wall 8 ofthe journal box recess. The end portions of the longitudinal or axiallyarranged ribs are shaped to extend about the corner bends which unitethe side walls of the side frame with the marginal inturned edgesthereof, as best shown in Figure 2; Lateral thrusts 'ofthe side framewith respect to the journal box are partly taken by the end portions ofthe ribs adjacent the aforesaid corner bends. The configuration of thejournal box top forms a desirable bearing surface contacting the sideframe and provides a strong construction of comparatively light weight.

The journal box is provided with means peri iitting its ready attachmentto the truck side frame, said means including spaced longitudinallydisposed lugs 16 and 17, said lugs embracing the respective inner andouter side walls of the side frame and each being provided with anopening 18. Registering openings 19 are provided in the side walls ofthe side frame and through the registering openings 18 and 1 9connecting pins or bolts 20 are inserted, as clearly shown in Figure 3.Each pin 20 is provided at one end with a head 21, the opposite end ofthe pin being preferably perforated to-receive the cotter22. The pins 20are preferably designed to fit loosely within the registering openingsinthe slde walls and lugs, thereby permitting the longitudinal thrustsofthe side frame to be principally taken by the abutment walls 6. and 7lining the journal box recess. The attaching lugs or projectionsprovided on the journal box are preferably slightly spaced from the sidewalls of the side frame to provide clearance which, together with therelatively loose pin-connections, permits any transverse.

the front and rear of the journal box, the beglnnmg of sald convergenceoccurring on a line passing through the center of the pin k openings 18provided in the lugs 16 and 17. The inclinations or angles of theseportions of each side wall are clearly shown in Figures 5 and 6, thehorizontal line (1*(1 passing through the center of the openings in thelugs indicating the. parting line of the mold in which the journal boxis cast for that portion of said journal box to the front and rear ofthe attaching lugs. Each side wall is provided with a portion betweenthe attaching lugs, each portion being converged upwardly and inwardly,the beginning of said convergence being'located in a horizontal planebelow the parting line aa, passing through the center of the pinopenings 18. The angle or inclination of this intermediate portiondisposed between the attaching lugs is best shown in Figure 7, the line22-45 indicating generally the beginning of the convergence of saidportion at a point where this portion of the mold is separated. Inpractice it is usual to core out this portion of the casting between theattaching lugs, and it is because of this practice that the convergenceof the side walls between the; lugs can be'lengthened with the advantageof permitting the use of a comparatively greater cross sectional area ofmetal in the pressed metal side frame between the outer journal boxabutment wall 7 and the extreme end of theside frame. The increase ofmetal in the side frame blank at these points, which are some of thecritical points of the side frame, is

of great benefit in resisting the strains incident to service conditionsMy improved method of manufacturing a journal box of the class referredto consists in shaping portions of the side walls of the journal box soas'to conformto the portion of the side frame with which the journal boxcontacts, said side Wall portions being inwardly converged at theirupper ends so as to provide for-the use of a maximum quantity of metalin the side frame and at the same time permit the portions of the sidewalls at the front and rear ofthe journal box to be so shaped as to beeasily cast in a mold which latter can be readily parted. It will alsobe noted that my improved mama journal box is arranged for production ina mold capable of being parted on the center line of the attaching pinopenings for that portion of the journal box which lies to the front andto the rear of the attaching lugs or projections. The portion of theside walls of the journal box between the attaching lugs is designed forparting below theline of the pin openings. This is dsirable in practicein order to obtain the advantageous side frame construction referred toherein, and at the same time provide a construction which will notinterfere with the molding of the journal box, because the portionbetween the pin lugs is preferably cored out, and the portions of theside wall outside of the pin lugs can be parted on the regular partingline of the mold which in my present embodiment is disposed in the samehorizontal plane or center line passing through the pin openings.
